Considering not only the consistency of evaluation information but also the contradiction of evaluation information, a weighting factor is introduced to achieve the equilibrium between conjunction operator and disjunction operator. The conjunction disjunction double operator weighted fusion rule designed by the invention can support the contradiction treatment in the product manufacturing process sustainability discrimination, and has the advantages of convenient application and easy programming realization.
